How can I prove to my friend that my girlfriend is hotter than his?

My gf is 2 inches taller than his. Has bigger, more voluptuous perfect for feeding the offspring. I often find myself imagining playing rollerboat with those two puppies. She also has a curvy and wide hips which is sign of fertility. She also has delicate female features where as his gf looks like someone who had one too many visits to a bar.
